Second year above ground pool owner and am quite bad at it. I have a 33' pool with a swim pro voyager cartridge filter. Filter and pump ran OK (i guess) last year. This year it runs up to pressure (12 lbs was normal last year) very rarely and most times i get 2 lbs of pressure out of it. A little background. The pool was left with leaves in it last year and I'm having quite the mess this year. The cleaning process is taking extra long this year becasue I have to keep messing with the pump/filter. Does anyone know how I can maintain a good pressure so I can get this done. Thanks.
